Open English WordNet (OEWN) is an open-source, community-maintained lexical database of English, forked from Princeton WordNet 3.1 and developed under the Global WordNet Association. It groups words into synsets linked by relations such as hypernymy, antonymy and meronymy, and is released yearly in WN-LMF XML, RDF, JSON and legacy WNDB formats.

Open English WordNet (OEWN) is a lexical network of the English language. Words are grouped into synsets (sets of synonyms sharing a sense), and synsets are linked by relations such as hypernymy, antonymy and meronymy. It is a fork of Princeton WordNet 3.1, which is no longer updated, and is maintained on GitHub under the Global WordNet Association with an open-source contribution model. Correspondence to earlier WordNet versions and to wordnets in other languages is provided through the Collaborative Interlingual Index (CILI).
New editions have appeared roughly yearly since 2019 (2019, 2020, 2021, 2022, 2023, 2024 and 2025). Files are served from https://en-word.net/static/ and attached to GitHub releases; there is no version-independent “latest” link, so products here point to the 2025 edition files.
Since the 2025 edition, proper nouns have moved to a separate resource, Open English Namenet, built from Wikidata. Two flavours are released:
Each flavour is available as WN-LMF XML, RDF (Turtle), JSON and legacy WNDB files.
OEWN is derived from Princeton WordNet under the WordNet License and further developed under CC BY 4.0. Attribution is required to both Princeton WordNet and the Open English WordNet team.
The 2019 Global Wordnet Conference paper describes the project’s origins. A later paper, “English WordNet 2020: Improving and Extending a WordNet for English using an Open-Source Methodology” (McCrae et al., LREC 2020 Multimodal Wordnets workshop), was not found in Crossref and is not listed above.
